it would take Cody 40 bushels / 5.26 bushels per hour = 7.61 hours to pick 40 bushels of apples alone.
How to find Lisa's individual work?To begin, let's determine Lisa's individual work rate, or the amount of work she can complete in an hour.
The work formula states that the amount of work completed is equal to the product of the work rate and the amount of time spent working. Lisa's work rate is 40 bushels divided by 13 hours equals 3.08 bushels per hour.
Let C represent Cody's work rate, and let t represent the amount of time it takes him to pick 40 bushels on his own.
At the point when Lisa and Cody cooperate, they pick 40 bushels, so we can compose:
Lisa's work + Cody's work = Total work
3.08 bushels/hour * 4.8 hours + C * 4.8 hours = 40 bushels
14.78 + 4.8C = 40
4.8C = 25.22
C = 5.26 bushels per hour
Consequently, it would take Cody 40 bushels/5.26 bushels each hour = 7.61 hours to pick 40 bushels of apples alone.

A boat leaves a pier and travels 15 miles due east, then turns and travels 15 miles in the direction N 20° E. Which diagram represents the boat’s current distance, x, from the pier?
(diagrams attached below)
Answer: 20.64 miles.
Step-by-step explanation: The assignment of nomenclature to the location of the boat's initiation as point A, the termination of the first course of the excursion as point B, and the termination of the second course of the journey as point C is proposed. The present study reveals that the spatial positioning of point A and point B is separated by a distance of precisely 15 miles in an eastward direction. Similarly, point B and point C are separated by a distance of 15 miles, but oriented along the vector of N 20° E.
The application of trigonometry provides a means to determine the spatial separation between point B and point C. Based on computations, the distance from point B to point C has been estimated to be approximately 7.83 miles along the northward direction and approximately 14.16 miles along the eastward direction.
Henceforth, the computation of the distance between point A and point C (i.e., the prevailing separation of the boat from the pier) can be determined by the ensuing method:
The mathematical expression denoting the distance between points A and C, designated as AC, is given by the square root of the sum of the squares of the distances between points A and B, designated as AB, and between points B and C, designated as BC. In formulaic notation, this can be expressed as AC = √((AB)² + (BC)²).
The magnitude of the distance denoted by AC, between two points A and C, can be calculated using the Euclidean distance formula, which involves the square root of the sum of the squares of the differences between the corresponding coordinates of the two points. In this particular case, the calculation results in the expression √(15² + 14.16²).
The distance between points A and C, denoted as AC, can be expressed mathematically as the square root of the sum of the squares of the horizontal and vertical distances between them. Thus, AC = √(225 + 200.89), where 225 and 200.89 represent the square of the horizontal and vertical distance, respectively. This equation can be simplified to yield the measurement of the physical distance between points A and C in the applicable units of length.
The distance between points A and C is determined to be the square root of 425.89 in units of length.
The measurement of the distance between point A and point C is approximately equivalent to 20.64 miles.

F(x)=x-1/x+1 show that f(2x)=3f(x)+1/f(x)+3?
The proof that f(2x)=3f(x)+1/f(x)+3 is shown below.
Mathematical functionTo show that f(2x) = 3f(x) + 1/f(x) + 3, we substitute 2x for x in the expression for f(x):
f(x) = x - 1 / x + 1
f(2x) = 2x - 1 / 2x + 1
Next, we substitute x into the expression for f(x) and add the result to itself twice:
f(x) = x - 1 / x + 1
f(x) + f(x) + f(x) = (x - 1 / x + 1) + (x - 1 / x + 1) + (x - 1 / x + 1)
= 3x - 3 / 3x + 3
We can simplify the expression by dividing both the numerator and denominator by 3:
f(x) + f(x) + f(x) = x - 1 / x + 1
= (1/3) (3x - 3) / (1/3) (3x + 3)
= (x - 1) / (x + 1)
= f(x)
Now, we substitute f(x) and f(2x) back into the original equation:
f(2x) = 2x - 1 / 2x + 1
3f(x) + 1/f(x) + 3 = 3(x - 1 / x + 1) + 1/(x - 1 / x + 1) + 3
= (3x - 3 / x + 1) + (1 / (x - 1 / x + 1)) + 3
= (3x - 3 + (x + 1) / (x - 1)) / (x + 1)
= (2x + 2) / (x + 1)
= 2(x + 1) / (x + 1)
= 2
Thus, we have shown that f(2x) = 3f(x) + 1/f(x) + 3.

A tap that runs at 1 litre per minute was turned on to fill the tank. It was left running for 158 minutes and some water spilt out of the tank after it was full. What was the volume of water that spilt out of the tank?
Step-by-step explanation:
Volume = 20×70×80 = 112000 cm³
Volume of cubes = 20×20×20 ×5 = 8000 ×5 = 40000 cm³
Volume of space in the tank = 112000-40000 = 72000 cm³ = 72000 mL = 72 L
Volume of water from tap = 158 × 1 = 158 L
Volume of water spilt out = 158 - 72 = 86 L
Answer: 30000cm³
Step-by-step explanation:

Determine if the function below is continuous.
A. not continuous
B. both continuous and not continuous
C. cannot be determined
D. continuous
A. not continuous
Step-by-step explanation:Continuous functions have no jumps or vertical asymptotes.
Continuity
For a function to be continuous, each point on the function must be defined. This means that there cannot be points on the graph where there is no value or coordinate point. Additionally, all points must be connected by the graph. Sudden jumps in the graph that are not connected by anything are not continuous.
Determining Continuity
The graph above is not continuous. We know this for 2 reasons. Firstly, the graph is not defined at x = -3. Since there is an open circle at x = -3, the value is not defined. Thus, the function cannot be considered continuous. Additionally, there are multiple jumps. At x = -3, the function suddenly jumps to x = -2 without the points being connected. The same thing happens again at x = 1. This also shows that the graph is not continuous.
A manufacturer records data on the battery life of a new product and discovers the data is normally distributed. The mean life of the battery is 120 hours and has a standard deviation of 10 hours. The manufacturer commits to replacing all batteries that last less than 100 hours. If 32,200 batteries were produced, how many would they expect to replace?
The firm expects replacing around 734 batteries out of the 32,200 produced.
How to determine how many batteries many would they expect to replaceusing the normal distribution formula z = (x - )
When z denotes the z-score,
x denotes the battery life of interest, is the mean battery life, and is the standard deviation.
For x = 100, use the z-score: z = (100 - 120) / 10 z = -2
Calculate the area under the normal curve to the left of z = -2.
0.0228 is the approximate value.
The number of batteries expected to be replaced by the manufacturer is equal to the proportion of batteries with a battery life of less than 100 hours multiplied by the total number of batteries produced:
Number of batteries to be replaced = 0.0228 x 32,200
734.16 batteries are expected to be replaced.
As a result, the firm anticipates replacing around 734 batteries out of the 32,200 produced.

Define equations?Equations are mathematical expressions that have two algebraic expressions on either side of the equals (=) symbol. It proves that the expressions printed on the left and right sides are equally valid. In each mathematical equation, we have LHS = RHS (left hand side = right hand side). Equations can be solved to find the value of an unknown variable that represents an unknown quantity. If there is no "equal to" symbol, a statement is not an equation. We'll consider that to be a term.
As per the question,

Total number of caps made = t
Total number of days = d.
Now, the required equation will be:
t = c × d

If you deposit $2000 in an account paying 2% annual interest compounded monthly, how much money will you have in the account after 40 years?
Answer: To calculate the amount of money you will have in the account after 40 years, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
where A is the amount of money in the account after t years, P is the principal (the initial amount of money deposited), r is the annual interest rate (as a decimal), n is the number of times the interest is compounded per year, and t is the number of years.
In this case, P = $2000, r = 0.02 (since the interest rate is 2%), n = 12 (since the interest is compounded monthly), and t = 40. Plugging these values into the formula, we get:
A = 2000(1 + 0.02/12)^(12*40)
A = $5,837.85
So you will have $5,837.85 in the account after 40 years.

Mrs. Smith made 6 ¼ dozen cookies for the birthday party. At the end of the party, there were 3 ½ dozen cookies left. How many cookies did the guests eat?
The guests in the birthday party ate 33 cookies.
How many cookies did the guests eat?We know that Mrs. Smith made 6 1/4 dozen cookies and there were 3 1/2 dozen cookies left.
Let's first convert these fractions to a common denominator of 4, so we can easily subtract them.
6 1/4 dozen = 25/4 dozen
3 1/2 dozen = 14/4 dozen
Now we can subtract the number of cookies that were left from the number of cookies that were made:
25/4 - 14/4 = 11/4 dozen
To find out how many cookies this represents, we need to multiply by the number of cookies in one dozen.
There are 12 cookies in one dozen, so:
11/4 x 12 = 33
Therefore, the guests ate 33 cookies.

a varies inverselv as b^3. If a =
3/2 when b = 2, find a
when b is 3
If a varies inversely as b³, the value of a when b=3 is 4/9.
Given that, a varies inversely as b³.
Here, a∝1/b³
a=k/b³
Substitute a=3/2 and b=2 in a=k/b³, we get
3/2 = k/2³
3/2 = k/8
3 = k/4
k = 12
Substitute k = 12 in a=k/b³, we get
a=12/b³
When b=3
a = 12/3³
a=12/27
a=4/9
Therefore, if a varies inversely as b³, the value of a when b=3 is 4/9.

Question 1(Multiple Choice Worth 2 points)
(Linear Functions LC)
Which of the following equations represents a linear function?
A x=1
B y=12²
C y-12-1
D4x-2=6
The equation that represents a linear function is D 4x - 2 = 6.
Which equation represents a linear function?A linear function is a function whose graph is a straight line. In general, the equation of a linear function can be written in the form y = mx + b, where m is the slope and b is the y-intercept.
Option A (x = 1) represents a vertical line passing through x = 1. Since the slope of a vertical line is undefined
Option B (y = 12²) represents a horizontal line passing through y = 144. Since the slope of a horizontal line is zero
Option C (y = 12-1) represents a horizontal line passing through y = 11. Since the slope of a horizontal line is zero
Option D (4x - 2 = 6) can be rewritten as 4x = 8 or x = 2. This is the equation of a vertical line passing through x = 2.
Therefore, the only equation that represents a linear function is D 4x - 2 = 6.
